I tried this in Windows with 'Drive Letter Access' and after 3 or 4 reboot and a lot of unknown errors, it did appear to be working. The UDF volume as burnt by Drive Letter Access was mounted r/w by the Linux kernel, but attempts to cp data to it were not successful.

I'm curious if this still works - my drive/media is also seeing similar issues. I have feeling this may have suffered some bit rot as well, but also can't discount the fact that the media or drive may have seen its better days.

I've got a TSST SH-W162C (PATA DL in a USB enclosure), SH-S203B (SATA DL connected to a SATA port), and a Pioneer DVR-A06 (PATA single layer, also USB). The recent test was on the SH-W162C, I will have to try on the others when I have a chance...

I know this was working in the past but was extremely slow, that's why I was suspecting bitrot... but since there was such a gap since I last tested it and the media/drive have degraded, I don't know...

but yes, since SAO is working I kind of suspect most of it should be working...

My SH-S203B works when I mkudffs --media-type=dvdram (not sure if this is legal) on a dvd+rw media and then subsequently mount /dev/sr0 /mountpoint ... No errors in syslog.

This drive is a "younger" drive (it has not written many discs but using old media that was failing in the SH-W162C which has written many discs (DVD-R and CD-R) in the past. Or it could be USB, need to test the Pioneer :)_________________Intel Core i7 2700K@ 4.1GHz/HD3000 graphics/8GB DDR3/180GB SSDWhat am I supposed watching?

... and it worked too! At least it was able to mount the udf DVD+RW disk.

... and tried it in my first writemaster... and it worked too!

Weird... Might have just been the initial format?

Currently trying to write one disk completely on my pioneer via direct access... so far so good, but it's very slow - indicating the disk or drive isn't in great shape. There are many spots on the disk that seem to stall, probably bad sectors - but some are zooming right along._________________Intel Core i7 2700K@ 4.1GHz/HD3000 graphics/8GB DDR3/180GB SSDWhat am I supposed watching?

and mounted it afterwards. This mkudffs was done on the "young" drive, I need to find another disk to try this on one of my older drives.

The initial dvd+rw-format on the "virgin" disk is still needed before mkudffs. But this format I did a long time ago for this particular disk, and this "format" should be the same as the one needed for Windows.

It doesn't make sense - if you formatted in Windows it should work in Linux too..._________________Intel Core i7 2700K@ 4.1GHz/HD3000 graphics/8GB DDR3/180GB SSDWhat am I supposed watching?
